SG350X-24P-K9-UK combines 24 Gigabit PoE+ access ports with four fixed 10G uplinks in a managed Layer 2+ switch. Two uplinks are dedicated SFP+ cages; the remaining two offer copper or fiber connectivity through shared 10GBASE-T/SFP+ interfaces. Four access ports support 60W PoE, while the other powered ports support 30W, subject to the shared power allocation. The Rack-Mount 1U chassis belongs to the Cisco 350X Series Stackable Managed Switches line for small-business networks connecting workstations, IP phones, wireless access points and surveillance cameras. The also-discontinued SG350X-24MP-K9-UK retains the same access-port configuration but raises its PoE allocation to 382W. Fixed uplinks support 1G operation as well as 10G, allowing existing lower-speed connections to remain in service during an access-switch replacement.

128 Gbps switching capacity supports nonblocking Ethernet switching across the access and uplink interfaces. 95.23 Mpps forwarding performance applies to 64-byte packets. 195W of shared PoE allocation requires endpoint loads to be sized together rather than treating every powered port as simultaneously available at its individual maximum. Static routing supports inter-VLAN communication, with 990 IPv4 static routes available for manually maintained paths. SG350X-24P-K9-UK pairs 512 MB of DRAM with 256 MB of flash for its operating software and configuration storage. The SG350X-24P maintains 16000 MAC addresses for Ethernet forwarding. STP/RSTP/MSTP controls switching loops, while LACP forms aggregated Ethernet links. Management includes a browser interface, scriptable CLI and SNMP monitoring. Two fans cool the chassis within its 0°C to 50°C operating range. 268.3W worst-case consumption with PoE loading is the maximum figure to carry into electrical and UPS sizing; that figure includes endpoint power rather than representing the switch electronics alone.

When an access refresh must retain local inter-VLAN gateways, the switch supports 128 IPv4 interfaces and 245 IPv6 static routes. Map existing gateways and manually maintained routes before choosing the replacement quantity. Specify the interface plan and confirm upstream routing responsibilities before the PO.
When several small-business locations are being staged from a common configuration, Cisco Network Plug and Play supports provisioning through Cisco PnP Connect. The embedded agent belongs in the deployment workflow rather than the hardware count. Specify provisioning credentials and the intended configuration handoff before placing the PO.
When staging equipment must reproduce a site's packet-size settings, the switch supports jumbo frames of 9000 bytes and keeps dual firmware images. Match the staging image and MTU to the installed network rather than assuming factory settings. Specify the staging image and packet-size validation plan before ordering.
Full-power PoE+ across every access port
SG350X-24P-K9-UK shares 195W across its powered ports; 24 endpoints each drawing 30W exceed that allocation. Simultaneous full-port PoE+ loading cannot be specified on this model.
Dynamic routing at the access edge
SG350X-24P-K9-UK routes through manually configured IPv4 and IPv6 static entries. Its routing feature set does not meet requirements for automatically learned routes or dynamic routing adjacencies.
Fanless operation in occupied spaces
Two fans cool SG350X-24P-K9-UK, so the chassis does not meet a fanless requirement. Acoustic output reaches 52.9 dB at an operating temperature of 50°C.

SG350X-24P-K9-UK identifies the Gigabit stackable model in the 350X series, with 24 PoE+ access ports; 24 gives the access-port count and P identifies the powered variant. The UK regional suffix covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia.
SG350X-24P-K9-UK supports an HTTP/HTTPS web interface, full or menu CLI through console/SSH/Telnet, and SNMP 1/2c/3. Network management integrations include Smart Network Application, Cisco FindIT Network Manager with the embedded FindIT Network Probe, and Active Advisor. FindIT Network Discovery Utility adds browser-based discovery and inventory visibility.
SG350X-24P-K9-UK is discontinued: end-of-sale was October 30, 2021, and Cisco's last support date is October 31, 2026. Software maintenance ended October 30, 2022. CBS350-24P-4X-UK was its initial replacement and is also discontinued; the migration chain now ends at C1300-24P-4X for new equipment purchases.
SG350X-24P-K9-UK is offered new sealed with up to 3-year extended ORM warranty or certified refurbished with up to 1-year ORM warranty; Cisco's limited lifetime hardware warranty ends October 31, 2026. Both conditions include 30-day returns, terms apply. Refurbished units are inspected, bench-tested, firmware verified and wiped to factory default.
SG350X-24P-K9-UK is a replacement for the discontinued SF550X-24P-K9-UK, which reached end-of-sale June 18, 2020. The earlier switch has 10/100 access ports, while this replacement provides Gigabit access. The replacement retains 24 powered access ports, but SG350X-24P-K9-UK itself is now a discontinued model.
SG350X-24P-K9-UK provides a shared 195W PoE budget across 24 powered access ports, with four ports supporting 60W and the remaining ports supporting 30W. Those individual port limits do not override the shared allocation. Add simultaneous endpoint requirements before ordering; 24 endpoints at 30W each would exceed the budget.
The SG350X-24P model supports two dedicated 10G SFP+ uplinks and two 10G copper/SFP+ combo uplinks, with one interface active per combo pair. Supported fiber options include SFP-10G-SR= for multimode connections and SFP-10G-LR= for single-mode connections. Match the transceiver to fiber type and link distance, and order the required optics separately.
The 350X series supports four hardware-stack members, including mixed SG350X, SG350XG and SX350X models. Stacking uses 10G copper or fiber interfaces and supports ring or chain connections. Supported copper cable options are SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M=. Reserve the necessary uplink interfaces and cable lengths when specifying the stack.
Yes, SG350X-24P-K9-UK supports static IPv4 and IPv6 routing between configured interfaces, including VLAN interfaces. Its limits are 990 IPv4 static routes and 245 IPv6 static routes, with 128 IPv4 interfaces. Routing uses manually maintained entries rather than dynamic route learning, so define the upstream routing responsibilities before deployment.
Yes, SG350X-24P-K9-UK is a Rack-Mount 1U switch with a chassis measuring 440 mm wide, 44 mm high and 350 mm deep. A mounting kit is included with the base package. Allow space for cabling and ventilation, and check rack depth and loading against the 4.93 kg unit weight before ordering.
SG350X-24MP-K9-UK provides a 382W PoE budget, compared with 195W on SG350X-24P-K9-UK, while retaining 24 Gigabit powered access ports. Both are discontinued models. Within an existing 350X installation, the MP model accommodates a larger aggregate endpoint load; the P model serves replacements whose combined power requirements stay within its smaller allocation.
SG350X-48P-K9-UK has 48 Gigabit powered access ports, whereas SG350X-24P-K9-UK has 24. Both are discontinued switches with four fixed 10G uplinks. The 48-port model serves legacy installations needing greater endpoint density in one chassis; the 24-port model matches existing lower-density replacements without adding unused access-port positions.
C1300-24P-4X provides four 10G SFP+ uplinks, while SG350X-24P-K9-UK combines two dedicated SFP+ uplinks with two copper/SFP+ combo uplinks. Both have 24 Gigabit powered access ports. The discontinued 350X model matches legacy copper-uplink replacements; C1300-24P-4X serves new purchases following the replacement chain and using SFP+ uplink connections.
The 350X series supports STP/RSTP/MSTP for loop control and LACP for link aggregation, with eight aggregation groups and eight ports per group. DHCP snooping and Dynamic ARP Inspection provide additional traffic validation. Define port roles and aggregation membership during staging; these switching controls are separate from the static routing configuration.
SG350X-24P-K9-UK has worst-case consumption of 268.3W at 110V AC with PoE loading, or 258.8W at 220V AC. Without PoE loading, its worst-case system consumption is 48.8W at 110V and 49.3W at 220V. Use the loaded figure appropriate to the supply voltage when sizing electrical circuits and UPS capacity.
